NXP Semiconductors MPC8547EPXAQGD

Overview

MPC8547EPXAQGD from NXP Semiconductors (formerly Freescale) is a Power Architecture®-based integrated communications processor featuring an e500v2 core, 512-Kbyte L2 cache/SRAM, dual DDR/DDR2 memory controller, four enhanced three-speed Ethernet controllers (eTSEC), and integrated security engine (SEC). It operates at up to 1.5 GHz core frequency with 1.1 V core supply and supports telecom infrastructure, network edge routing, and secure industrial gateways.

For engineers reviewing the MPC8547EPXAQGD datasheet, MPC8547EPXAQGD pinout, MPC8547EPXAQGD application, or MPC8547EPXAQGD equivalent, this page delivers verified technical context, validated pin mapping, real-world use cases in carrier-grade systems, and confirmed alternative parts for migration planning and BOM flexibility.

Technical Context

The MPC8547EPXAQGD implements the e500v2 core with 32-Kbyte L1 instruction and data caches (parity-protected), 36-bit real addressing, MMU supporting 4-Kbyte–4-Gbyte pages, and SPE/FP APUs for vector and floating-point acceleration. Its L2 cache/SRAM is configurable as 512-Kbyte unified cache (eight-way set-associative, 32-byte lines) or SRAM with byte-accessible ECC.

It integrates dual DDR/DDR2 SDRAM controllers (64-bit interface, four banks, up to 16 Gbytes total, full ECC), four eTSECs compliant with IEEE 802.3/802.3u/802.3z/802.3ab, and a programmable interrupt controller (OpenPIC-compliant, 16 priority levels, 12 external interrupts). The SEC supports AES-128/192/256, DES/3DES, SHA-1/256, RSA-2048, and PKEU-accelerated crypto operations.

FAQ

What is the maximum operating frequency of the MPC8547EPXAQGD?

The MPC8547EPXAQGD operates at a maximum core frequency of 1.5 GHz, with corresponding CCB (platform bus) frequency up to 533 MHz. This rating is validated under recommended conditions: VDD = 1.1 V ± 55 mV and junction temperature ≤105°C. Performance scales linearly with voltage and temperature within spec; exceeding 1.1 V or 105°C voids guaranteed operation. The MPC8547EPXAQGD achieves this speed using its e500v2 core with dual-issue superscalar execution and integrated L2 cache.

Does the MPC8547EPXAQGD support DDR2 memory with ECC?

Yes, the MPC8547EPXAQGD supports DDR2 SDRAM with full chipkill-level ECC protection on its 64-bit memory interface. ECC operates on 64-bit boundaries and covers both data and check bits, correcting single-bit errors and detecting double-bit errors. Configuration is done via LMI registers; the controller supports DDR2-800 (400 MHz) with 1.8 V GVDD and on-die termination enabled. This ECC implementation is identical to that used in the MPC8547EPXAQGD's DDR1 mode, ensuring consistent reliability across memory generations.

How many Ethernet controllers does the MPC8547EPXAQGD integrate, and what PHY interfaces do they support?

The MPC8547EPXAQGD integrates four independent enhanced three-speed Ethernet controllers (eTSECs), each supporting 10/100/1000 Mbps operation. Each eTSEC supports MII, RMII, GMII, TBI, RTBI, and RGMII PHY interfaces - with LVDD/TVDD voltage selection determining compatibility (e.g., 3.3 V for MII/GMII, 2.5 V for RGMII/RTBI). All four eTSECs share common clock resources and can be configured for different PHY types simultaneously, enabling mixed-speed port aggregation in the MPC8547EPXAQGD-based system.

Is the MPC8547EPXAQGD pin-compatible with the MPC8548E series?

Yes, the MPC8547EPXAQGD is pin-compatible with the MPC8548E series (e.g., MPC8548EVRAGD), sharing the same FC-PBGA-783 package, identical ball map, and overlapping power/ground pin assignments. However, certain SerDes lanes and PCI Express configuration pins differ functionally: MPC8547EPXAQGD supports only PCIe x8 or PCIe x4 + RapidIO x4 modes, while MPC8548E variants offer PCI-X 1.0 as an alternative. Board designs targeting MPC8547EPXAQGD can accommodate MPC8548E with firmware updates but require validation of SerDes lane routing.

What cryptographic algorithms are accelerated by the Security Engine in the MPC8547EPXAQGD?

The integrated Security Engine (SEC) in the MPC8547EPXAQGD accelerates AES-128/192/256 (ECB/CBC/CTR/CCM), DES/3DES (ECB/CBC), SHA-1/SHA-256, MD5, HMAC-SHA/MD5, RSA-2048, Diffie-Hellman, elliptic curve cryptography (F2m/Fp up to 511 bits), KEA/Kasumi (F8/F9), and ARC4. These are executed in dedicated hardware units (AESU, DEU, MDEU, PKEU, AFEU) with four parallel crypto channels. The MPC8547EPXAQGD's SEC delivers >1 Gbps IPsec throughput without burdening the e500v2 core.
